"Such a fun way to kick off the school year! My students loved making their own chalk, and it gave us an easy, hands-on way to talk about physical and chemical changes."

— Ms. Dana Foster, 3rd Grade Teacher

"I couldn’t believe we actually made chalk! My favorite part was taking it out of the mold and getting to draw with something we made ourselves."

— Owen T., 3rd Grade Student
